[P2] scale json polygons

[titmael]

Hi,

 

I have a sprite and a corresponding json physics for collision polygons.

 

I know how to scale a sprite, but how can I scale the polygons at the same time ?

 

I read http://www.html5gamedevs.com/topic/4795-it-is-possible-to-scale-the-polygon-with-p2-physics/ but was for polygons created in code.

Thx
